MISTERLP
"It's time for Genia..."
"...a-and Merula's..."
""...Let's Test It!""
The two who shouted this and pumped their fists into the air were
overscientist Genia, who had just gotten engaged to Ludwin Arcs, the
Captain of the Royal Guard, the other day; and Merula Merlin, from the
Spirit Kingdom of Garlan, the high elf whose too-strong curiosity had
gotten her accused as a witch, and put her on the run from the Orthodox
Papal State of Lunaria.
The two of them were now in the ruined dungeon workshop owned by
the House of Maxwell.
"...Um, was there some meaning behind that call?" Merula asked
Genia, her pale face having turned red.
"Huh? It was obviously just a spur-of-the-moment thing."
"Spur-of-the-moment...? Now, listen, Genia..."
"C'mon, Merumeru. Time's finite. Let's get to testing!"
"Please, don't call me Merumeru!"
Ignoring Merula's protests, Genia pulled something out from behind
her. It was a squalid bag, about the size of a sandbag used in boxing
practice.
"This here is the item up for testing today," Genia declared. "Dun-dudu-duuun: the Hero's Sack."
"The Hero's Sack?"
"This sack was said to be used by the first King of Elfrieden, who, just
like our king (Souma), was summoned from another world as a hero. It
may not look like much, but it can hold a lot, and recently Sir Poncho's
been using it to store the ingredients he gathers all over the continent and
brings them back."
"The first king... Wait, isn't this a real treasure?" Merula asked, poking
at the sack.
If this was the first King of Elfrieden they were talking about, he was a
great hero who united the many races to form this kingdom. His story was
told of in legend, and he was still loved and respected by the people. If the
first king had used this, it was probably an incredibly prized possession.
"It's technically a national treasure, yeah," Genia said like it was no big
deal.
"N-National treasure?!" Merula jumped back in surprise. "Wait, is it
okay to treat a national treasure so poorly?!"
"When I told the king 'I want to study it,' he said, 'Don't break it,' and
let me borrow it."
"So easily?! Like you were asking to borrow a new pocket watch that
he just bought?!"
"It sounds like the king wants to research overscience relics," Genia
shrugged. "You think something happened?"
"I-I wouldn't know..."
Having learned there was a connection between his former world and
this one after the incident in the Star Dragon Mountain Range, Souma
directed his research organizations to do more specific research into the
overscience relics that were no doubt key to learning what the connection
was. He hadn't gone so far as to explain that situation to them, though.
"Anyway, today I think we'll run tests on the Hero's Sack." Genia
picked up the relic. "Now first, let's see about its weight and volume. As
you can see, at present, even a delicate basement-dweller with thin arms
like me can easily lift it up."
"Was the self-deprecation necessary? But yes, it certainly does look
light."
"But, get this, there's already a whole lot of stuff inside. Okay, my
golems, bring it on out."
With that, Genia had the dirt golems she made with her own ability
bring over a large, rectangular water tank. It had to be as large as a sizable
shed. The base was about four by five meters, and it was more than four
meters tall. Genia had to put up a ladder just to stand on the edge of it.
Merula, who was left looking up at her, asked, "Um, Genia? What is
this for?"
"The thing about this sack is, it's already been left immersed in a river
for half a day."
"What are you doing to a national treasure?! Won't you be punished?!"
Merula was confused, but Genia didn't care.
"We can't let little things get in the way of academic progress."
"I... I always thought I was too obsessed with research, but... it's a big
world out there."
"Haha! Please, don't compliment me like that, Merumeru."
"I'm not complimenting you!"
"Well, anyway, thanks to being immersed in the river for half a day,
there's a lot of river water inside here. We don't know its volume, so it
remains unknown whether it's full or not. Regardless, I think if we open
the sack into this water tank, we can find out how much water is inside. If
it gets dangerous, we can just close the sack up, after all." With that, Genia
turned the sack toward the water tank. "Now, the grand opening."
With that easygoing proclamation, Genia opened the sack and water
started gushing out with incredible force. The kickback made Genia lean
backward despite herself, but she managed to prevent it from becoming a
problem by having her golem servants hold her in place.
The water kept building, and in no time, the tank was already half full.
Because it had been filled with river water, it was muddy, and there was a
lot of algae, chunks of driftwood, and garbage inside.
"Oh, fish..." Merula, who was looking up from below, noticed a
number of fish swimming inside the tank. They must have gotten inside
while it was immersed in the river.
Setting aside everything else, the fish in the bag were still alive. This is
fascinating. I don't know what the bag is like inside, but at a bare
minimum, it has the conditions necessary to support living fish.
Merula tended to get dragged around by Genia, but she was every bit as
curious. She quickly shifted her mind into research mode and began
analyzing.
The water, which it seemed might come out infinitely, eventually came
to a stop with the tank nine-tenths of the way full.
"Hmm," said Genia. "It's unthinkable that this was all that came in
after it was immersed in the river for half a day. Therefore, this might be
right around the capacity of the sack. More or less than one shed full?
Normally, if there was this much water inside, I wouldn't be able to lift it.
Does that mean the weight of the things inside can be ignored?"
Having come down from the ladder, Genia speculated with her hand on
her chin.
"It's incredible to be able to ignore the weight of so much water..."
Merula pondered. "Oh! Look, Genia. Can you see the fish swimming in
the tank?"
"Hm? ...You're right. They're swimming around full of energy."
"Are they so energetic because it was just half a day? But there's no
light inside, right? Even if there was water the whole time, they'd probably
think it was night and be more sluggish."
"The fish inside are energetic, huh... There's something about that fact
that catches my attention. If I recall, the king said food that gets put inside
doesn't rot easily. If that's the case..."
The girls traded arguments that seemed to go nowhere.
While they did, there were two men watching them from the terrace of
the log cabin built inside the ruined dungeon workshop. One of them was
the Captain of the Royal Guard, Ludwin Arcs, who was Genia's fiancé.
The other was Merula's guardian (?), Souji Lester, the rotten bishop sent
from the Orthodox Papal State of Lunaria.
The two were drinking beer on the terrace while watching the women
engaged in their research. One wore a dumbfounded smile, and the other
was holding his head.
"That Genia, being reckless again." The one holding his head was
Ludwin. Today, like every day, the serious Captain of the Royal Guard
was being jerked around by his childhood friend Genia. "Did she say she
left a national treasure in a river for half a day? What was she thinking?! If
it got lost, they'd do more than just abolish the House of Maxwell!"
"Hahaha!" Souji laughed jollily as Ludwin clutched his head. "Oh,
what's the harm? Either way, during your generation, the Houses of Arcs
and Maxwell will merge to become the House of Maxwell-Arcs, right?"
"Urgh, that's not the problem! Besides, should you be letting Madam
Merula run wild, Sir Souji? You're her guardian, aren't you?"
"Even if you call me her guardian, my job's just to take it easy and
avoid acting on the requests my country sends me," Souji said. "I'll protect
her from the demands of my country to arrest her, but I don't care enough
to open my mouth about anything else. When it comes to anything other
than research, she's got her act together better than I do, anyway."
While saying that, Souji knocked back his beer. Normally, a man of the
cloth in the Lunarian Orthodox faith would be expected to refrain from
such worldly desires, but he was as rotten as ever.
"Phew..." he added. "When it comes to one of us telling the other off,
it's Merula that's the noisy one, you know? It's always, 'Clean up this
room,' or, 'You're acting like a slob. Get it together.'"
"No, I think Madam Merula is right... They're both researchers, but the
way she's neat and tidy is like the polar opposite of Genia."
"You might be surprised to find you'd be better off getting together
with Merula instead, don't you think?" Souji asked.
"By the same token, if we paired you up with Genia, I think the two of
you would run even more wild than you do now."
Imagining the pairings of Ludwin and Merrula, and Souji and Genia...
The two of them smiled wryly. That was because though it resulted in
couples with similar personalities, they just didn't feel right.
"Well, it's hard for things to work out when both partners are too
similar, after all," Souji said.
"...Is that how it works?"
While the two were having that sort of heart-to-heart talk, Genia waved
Souji over. "Hey, you got a minute, Old Man Souji?"
"Hm? You mean me, Young Miss Genia?"
"Yeah. Sorry, but could you come over here for a moment?"
"Geez, I guess I'll have to..."
With steps made slightly unsteady by alcohol, Souji headed over to
where Genia and Merula were.
Being called out by name when Genia was experimenting...
Ludwin had a bad feeling about this. But if he stopped the man from
going, he was bound to be the one to eat a stray bullet instead, so he shut
up and watched Souji go.
—Slightly before Genia called Souji over—
"I suspect the reason why food that's put in the sack doesn't rot easily
is because the time it takes the food to rot is being extended," Genia said.
"By which you mean?" Merula asked.
"I think the flow of time inside the sack is different from the flow of
time outside the sack. Perhaps the reason the fish that had been inside for
half a day were still so energetic also stems from the flow of time being
different. So, here's the idea."
Genia pulled out an hourglass. When turned upside down, the sand that
was filling the top part began falling to the bottom. Genia put the hourglass
into the sack in that state.
"This hourglass is designed so that it takes five minutes for all the sand
to reach the bottom. We'll wait five minutes with it like this."
"...I see. So that's how it is."
—Five minutes later—
When Genia pulled out the hourglass, the sand still hadn't fully fallen.
More than that, there was little change in the amount of sand at the top at
all.
Genia brought her hand to her chin and groaned. "Hrm... I expected the
sand not to have fully fallen, but if the amount in the top hasn't noticeably
changed, does that mean time is practically stopped?"
"Time's stopped inside this bag?! Is that possible?!"
"Our common sense doesn't apply when it comes to the way
overscience relics work, my dear Merumeru."
"Don't call me that... But how can we tell if time is stopped inside or
not?"
"Hm... It seems we're forced to use our last resort."
"L-Last resort?"
Merula gulped as Genia flashed her an indomitable smile.
"Going inside to see."
And that was why Souji was called over.
Merula turned a cold look on Genia. "So you're not going to go
inside."
"I am an observer," Genia said. "I have a duty to leave records of the
experiment."
"Honestly... This is really going to be okay, right?"
"You're worried about the old man?" Genia smirked, and Merula
turned to look away.
"Even if it was him, I'd have trouble sleeping at night if anything were
to happen."
"It'll be fine," said Genia. "You saw how energetically the fish were
swimming around, didn't you?"
"They may have looked that way on the surface, but there's no way to
tell if the fish are really fine when they don't speak."
Then Souji came over. "You called, Young Miss Genia?"
"Hee hee! I know this is sudden, but we're going to have you help us
out a little."
"Help? ...Wait, whuh?!"
Without waiting for his response, Genia pulled the Hero's Sack over
the top of Souji.
